• Modify the script for multiple virtual machines

  I'm working on the powercli user to change the CPU and the memory of several virtual machines.

  I found the perfect scenario created: http://ict-freak.nl/2010/05/07/powercli-script-to-schedule-memory-and-or-vcpu-updowngrade/comment-page-1/#comment-20336

  But it's only for 1 VM.

  Can someone tell me to change so do several virtual machines.  A text file would be ideal, but I'm ready for anything as this point, nothing I try does not work.

  Thank you.

  You could do

  foreach ($vm in Get-VM-name (Get-Content:\Powercli_scripts\servers.txt))

  I don't know why it's poweroffs randomly.

  You can add the - WhatIf parameter on this line, like that it will only say what he does, without actually running the cmdlet.

• Problem with networking when having multiple virtual machines on a single host

  Since the implementation of ESX 3.5i server on PowerEdge 1850 Server I had network problems. It took a large upstream of the violin - do not do something specific - but finally I could persuate a VM to talk to the outside world.

  Virtual machines have always been able to ping other virtual machines and physical NETWORK card to the host (with a static IP address only), however with a bit of deactivation/activation etc I could possibly get it connected. I have exactly the same symptomsusing the two Windows XP and Redhat, both with VM Tools installed.

  If big, I can get the virtual machines connected, *however * every time I managed to connect a computer to the outside network, she will knock off either a return to the State where I can ping only the other VMs and Teddy.

  I tried them in different port groups as well as in different vSwitches with a separate Teddy, but exactly the same problem.

  I thought it was just my ignorance, however after thorough reading and wasting time trying different combinations, I started to think this is a hardware incompatibility or an ESX installation problem.

  Please please please, if someone can help solve the problem, or diagnose if my suspicions are correct.

  I enclose my last combination of configurations!

  Thanks in advance.

  Run 'show port-security' on the switch and see what you have.  You can also view the current configuration of the port connected to an esx.  A switch will remove any doubt relating to port config differences type.

• Seen the share of multiple virtual machines to a VMDK master?

  I remember in VMware Server 1 I had a master VM and then by snapshots have an action series of computer virtual child as the initial configuration. In the VMDK level who would like to say that only the changes apply to every new VMDK and save disk space.

  In VMWare server 2, I can only have a snapshot at a time and so I can't do the above. Is there another way to do the same thing?

  Thanks in advance

  Are you sure that it wasn't the Server VMware Workstation?

  I don't remember that this feature was available on VMware Server...

• Single VMDK for multiple virtual machines in esx3.5?

  Hello

  Is it possible to use a single VMDK to host several VM in ESX3.5 or is this feature on the way?  I think the vmware view tech that allows you to host multiple virtual machines to a single image and store only the deltas for VMS replca.

  We organize several ts who are about 12 GB per image, and each server is essentially the same.  It would reduce the space if these could be consolidated at the level of vmware.

  Thank you very much.

  What you are referring to the notion of linked Clones, it's something completely different to share a single VMDK.  with linked clones, you actually run mulitple copies of a single Machine.  This fuinctionality is not available in ESX Raw but is a characteristic of Lab Manager and VMware View Premium.

• What is the advantage to affect multiple virtual machines in a data store?

  Hello

  Quite a question stupid and basic, but I can't answer . What is the advantage of having multiple virtual machines in a store of VMFS data instead of having each VM in another VMFS data store? (eg. 3 VMs in 1 data store or 3 data warehouses and each virtual machine in one of them). I can only think about the ease of management for storage administrator because it creates only a single large LUN.
  
  Thank you

  By allowing multiple virtual machines in a data store, you can run more than 256 virtual machines in a DRS cluster.

  As a host has a limit of 256 scsi identification numbers, which means that it accesses no more than 255 LUNS shared. 1 scsi ID is used for local storage.

  In a DRS cluster as each host must be mapped to the same data warehouses to ensure that virtual machines can be moved on the cluster and run on any of the hosts.

  Now in my life as an architect VMware PSO I saw that a lot of virtual machines that require a single data store. The main reason to isolate a virtual machine on a data store must provide sufficient i/o performance. This can be achieved with other solutions than to isolate a virtual machine on a data store. Having a properly architected storage subsystem is crucial, vSphere can get out of a very large number of the IOPS / s. With technologies such as SIOC and DRS for storage, you can check that the virtual machines receive IO performance according to the needs.

• Script to create multiple virtual machines model works is not for the network adapter variable

  We are working on a script to create multiple virtual machines from a template. The script works fine, but when we try to include commands to set the NIC to a group of specific ports on a dvswitch script errors on. Here's what we have so far. This script (less network variables) works, but we would like to include the network configs in the script as well.

  -------------------

  This is the part of the script that configures the network/dvswitch adapter... but does not work properly.

  $myResourcePool = get-ResourcePool-name DQOL

  $dsName = get-Datastore-name "DQOL-DS01.

  $myTemplate = get-Template-name "DQVTemplate".

  $distributedSwitchPortGroup = get-VirtualSwitch-distributed - name "CVE-dvS04-Nexus - k 5 | Get-VirtualPortGroup-name '979-DQ-SHARED '.

  New-VM-name MyVM1-model $myTemplate - Networkname ResourcePool - $myResourcePool - OSCustomizationSpec $mySpecification $distributedSwitchPortGroup - Datastore

  (Get-$dsName data store)

  New-VM-name MyVM2-model $myTemplate - ResourcePool $myResourcePool - OSCustomizationSpec $mySpecification - Datastore (Get-$dsName data store)

  _____________________

  !!!!!!!  This part works, but without specifying a network/dvswitch... card!

  $myResourcePool = get-ResourcePool-name DQOL

  $dsName = get-Datastore-name "CVE-SAN-ISG-DS02-02ef.

  $myTemplate = get-Template-name "DQVTemplate".

  New-VM-name MyVM4-model $myTemplate - ResourcePool $myResourcePool - OSCustomizationSpec $mySpecification - Datastore (Get-$dsName data store)

  Here is the error we get:

  You cannot use the - model and Networkname - parameters of the cmdlet New - VM in a single order, because both are in different parameter sets. You must first create the virtual machine and then use the cmdlet Set-NetworkAdapter to change the portgroup of the virtual machine. As in example 4, assistance from cmdlet Set-NIC:

  --------------  Example 4 --------------

  C:\PS>$myNetworkAdapters = Get - VM | Get-NetworkAdapter-name "NIC 1.
  $myVDPortGroup = get-VDPortgroup-name MyVDPortGroup
  Together-NetworkAdapter NetworkAdapter - $myNetworkAdapters - $myVDPortGroup Portgroup

  Retrieves all network named "NIC 1" cards of all virtual machines and connects to the specified distributed port group.

• Cannot start multiple virtual machines.  Maybe I corrupted the model

  We had problems with disk space, and I was looking around to see if he had left garbage data store.  I am very new to VM, but even though I'm new I'm responsible for helping maintain.  So I learn a lesson the hard way.

  I found a number of virtual machines in organized which did not seem to relate to existing models.  For example, we have a model name 000729-Server2008 Server 2008, that they are in lm401\729.  But it appers to be a clone of 729 to lm401\16.  I'm going to guess that 16 was the original version and changes or clones have been made for him and we are now sitting to 729.

  Then I moved 16 in another data store, but it failed because there is a lock on the hard master.  So I moved everything back.  Now, when we try to start up of VMs driven from this model we get "file & lt; filename not specified & gt; not found"I went back and tried to deploy and supply on the model but I get

  Impossible to deploy virtual machines in the pool of resources 'resgroup-131.

• Help for a demo: create multiple virtual machines

  Hello

  I am a beginner in vCO, I completed the installation and configuration with success and I started to create workflows, but I guess that I need help with an example that I started yesterday:

  I am creating several virtual machines at the same time, I mean all the user have to do is say how VMs, he wants to be created and the workflow must do the rest, but I don't know what is the best way to do so, in the present workflow in the library , find us only 'create simple VM' so I added a few scriptable tasks to this workflow, but still can't do what I want.

  Any solution plese? or a few best practices to perform this type of workflow? Maybe I missed a workflow can create multiple virtual machines with different names but the same configuration.

  Thanks in advance,

  This can help out you.

• Sharing the drive between several virtual machines

  Hi all

  We have a configuration with a SAN (Dell Compellent) and use vSphere 6 to host a number of Windows servers. We now have a giant machine of Windows with a large number of small files for a particular application.

  Now, we would like to create a cluster with a LoadBalancer in front of him, so that we can handle more load. To do this, we want to create a disk that is shared between 2 (or more) of windows machines.

  One of the problems is that NTFS is not a supported clustered file system. So, I did a lot of research on Google to see what my options are. In my opinion, they are the following:

  1. set up a Cluster Shared Volume (CSV) Microsoft (use SMB if I read the documentation)

  2. the user Windows shares on a separate file server

  3. the user NFS (depreacted under Windows)

  4. switch to Linux and use NFS

  The problem I have, is that they use all the network traffic. For example, option 2 is ridiculous slow. NFS under Linux is also a way slower than the local drive (managed by VMWare iSCSI) disk access and NFS on windows does not appear to be

  support very well.

  I know that there are aware filesystems, clustered as VMFS etc. Is there a way to access it directly from my Windows VM or are there devices SAN which is directly accessible from the virtual Windows machine?

  Or maybe there are other solutions to set up a shared drive?

  I know that there are aware filesystems, clustered as VMFS etc. Is there a way to access it directly from my Windows VM or are there devices SAN which is directly accessible from the virtual Windows machine?

  VMFS is a really clustered file system and allow access of multiple virtual machine the same amount of storage (data store) which is different from that to create a virtual disk (hard) and present to multiple virtual machines. You can do this, BUT the guest virtual machine should take care of several accesses to the hard, for Windows, you must turn on the feature... without this clustering with failover data may be corrupted.

  I think the best and supported solution for you is to create another cluster with Failover Cluster functionality and create a resource sharing files with files that will access your NLB nodes.

• Is it Possible to access only bypassed FC HBA to multiple virtual machines

  Hello

  I have a FC HBA on my 5.5 ESX. Server. It does not support the function of SR - IOV. Is it possible to access this FC HBA across multiple virtual machines?

  If possible, please provide as follows to go further.

  Kind regards

  Aashish

  It is not possible. The basic material underlying PCI specification does not have a single shared between several independent operating systems PCI device.

  SR - IOV solves by creating the virtual function peripheral PCI, but as you mentioned, that he can't stand not and first of all, ESXi supports that SR - IOV for Ethernet network devices and not for native FC HBA (excluded FCoE) functions.

• Stop/start multiple virtual machines with names created automatically

  Hi all

  in my test environment, I want to stop or start multiple virtual machines via the script.

  Their name is always like this:

  'vm-100-qa', 'vm-101-qa","vm-100-qa","vm-102-qa '...

  Now I would like to just stop every VM 'vm-140-QA' to 'vm-160-qa.

  I created a table "$a = 140.160", but I don't know how to implement this in a script 'Shutdown-VMGuest-comments '.... »

  Sorry for this stupid question. I am a beginner absolute powershell.

  Thank you very much in advance,

  Thank you

  Yes, you are right.

  By specifying the param -VM (Get - VM $modelVM) , you create the new virtual machine from an existing one.

  Just change the cmdlet New - VM settings according to your needs and let the VM - far.

  It creates your virtual machines based on a template and specification of customization.

  $esxName = "prodh1.MYDOMAIN.local"
  $template = "W2K8R2SP1"
  $datastore = "IOMEGA"
  $newVmList = "TEST-SRV01", "TEST-SRV02", "TEST-SRV03", "TEST-SRV04"
  $custSpec = "W2K8R2SP1"
  $location = "_Tobedeleted"
  $taskTab = @{}
  
  # Create all the VMs specified in $newVmList
  foreach($Name in $newVmList) {
       $taskTab[(New-VM -Name $Name -VMHost (Get-VMHost -Name $esxName) -Template $template -Datastore $datastore -OSCustomizationSpec $custSpec -Location $location -RunAsync).Id] = $Name
  }
  

  Of course, you can write it as before. You will need to only change the $newVmList variable in the original script.

  foreach($Name in $newVmList) {
       $taskTab[(New-VM -Name $Name -VMHost "prodh1.MYDOMAIN.local" -Template" W2K8R2SP1" -Datastore" IOMEGA" -OSCustomizationSpec "W2K8R2SP1" -Location "_Tobedeleted" -RunAsync).Id] = $Name
  }
  

  You will also need to insert the remaining part with the while loop and the customizations in your network!
